MSQuic fails when PublishSingleFile=true

[ladeak]

Description

I have a .NET 10 (same behavior on .NET 11) application, console app with the following csproj:

<PropertyGroup>
   <Http3Support>true</Http3Support>
</PropertyGroup>

When published:

dotnet publish MyApp.csproj --configuration Release --self-contained --runtime win-x64 -p:PublishSingleFile=true --framework net10.0

It seems HTTP/3 requests with the HttpClient fails:

Request Error System.Net.Http.HttpRequestException: Requesting HTTP version 3.0 with version policy RequestVersionExact while unable to establish HTTP/3 connection.
   at System.Net.Http.HttpConnectionPool.ThrowGetVersionException(HttpRequestMessage request, Int32 desiredVersion, Exception inner)
   at System.Net.Http.HttpConnectionPool.SendWithVersionDetectionAndRetryAsync(HttpRequestMessage request, Boolean async, Boolean doRequestAuth, CancellationToken cancellationToken)
   at System.Net.Http.SocketsHttpHandler.<SendAsync>g__CreateHandlerAndSendAsync|115_0(HttpRequestMessage request, CancellationToken cancellationToken)
   at System.Net.Http.HttpClient.<SendAsync>g__Core|83_0(HttpRequestMessage request, HttpCompletionOption completionOption, CancellationTokenSource cts, Boolean disposeCts, CancellationTokenSource pendingRequestsCts, CancellationToken originalCancellationToken)

Reproduction Steps

Please see the steps above.

Expected behavior

HTTP/3 requests succeeds the same way as without the PublishSingleFile flag.

Actual behavior

Request Error System.Net.Http.HttpRequestException: Requesting HTTP version 3.0 with version policy

Regression?

No response

Known Workarounds

No known workarounds. It works if I copy the msquic.dll next to it, but this is not a good way to distribute an application.
